Conditions for the establishment of milk kinship and the effects resulting from it

Question:
Following this, a message was received by the program from one of the listening brothers. The sender is your brother (Ibrahim . A. M.). Brother Ibrahim has some questions, one of which is: What is the ruling on marrying a milk sibling? And if this occurred without anyone knowing about the breastfeeding except the ignorant mother, is the marriage annulled after it has actually taken place, or not? And are all the children prohibited from marrying each other, or only those before the breastfeeding process was completed? May Allah reward you with good.

Answer:
The question is vague. Once milk kinship is established, meaning once it is established that Zayd was breastfed by so-and-so, it becomes forbidden for him to marry her daughters and her sisters. This is because her daughters are his milk sisters, and her sisters are his milk aunts. Therefore, he must be cautious of this, because breastfeeding prohibits what blood relation prohibits, as the Prophet (peace and blessings be upon him) said: However, the breastfeeding must be established by the testimony of a just woman, or more, that she breastfed him five times within the two-year period. The breastfeedings must be five, and they must be within the two years before the child is weaned. And the witness must be just, whether male or female, or more than one.
If the female witness is not known for her justice, her testimony is not established, and the same applies to the man. The witness to the breastfeeding must be just, whether from men or women. Yes.
